Data Catalog multi view

Hi, We have a question on Dendo 7 Data Catalog. Does “Data Catalog” tool support querying data across multiple views or user can only query on a single view at a time like how it used to be with ISS (information self service tool in denodo 6). It would be useful for us to know. Thanks.

Hi, To query multiple views at once, I used the association feature. If there is an association between two views with cardinality one, you can select the fields the fields on the second view while querying the first one from the relationship fields column in the Query window. Alternatively you can always join/union multiple views in the admin tool to create a derived view and users can use that derived view in the data catalog to see the results. For more information, please refer to the Relationship fields section in the [Query of views](https://community.denodo.com/docs/html/browse/7.0/vdp/data_catalog/browse/views_browse/query) in the data catalog guide. Hope this helps!
